I threw in a different trans but I had a problem 1st/rev before.

I resurfaced the flywheel put in a new 914 disc, used (spec good) P.Plate and adjusted it up. I had to use clearanced bolts on the fly.

I still got the crunchies, any suggestions?

Did you adjust the ball/cup throwout arm pivot with an extra shim washer to make up the difference that the flywheel lost from being turned?

Makes a difference as the arm needs to be closer to be adjusted right.

Or just adjust the clutch freeplay tighter and shift slowly.

If all the parts/gears/synchros,sliders are within spec it should shift nicely. How were the synchros,dogteeth and sliders?

Reverse crunches when you have a clutch issue.

Make sure you have the stop on the pedal board adjusted far enough up so you get full disengagement.

Also check for a moving clutch tube and the items Geoff mentioned.

Oh great I have to drop the engine again???
The season is almost over and I'm too busy, so I guess it will be a spring job. I'll try James trick first, I'd rather try a different box before I rip into this one, I've got 4 more sitting here.
Oh well! (IMG:style_emoticons/default/huh.gif)

You can just drop the tranny. It's easier than dropping both together and weighs a lot less.

I might do that, but it will still be at least next weekend before I can.

Been there, just did that.

Same issues, had to drop the friggin tranny TO INSTALL A WASHER!!!

Took me a good chunk of a Saturday, but the crunchies disappeared (OK, 1st at a stop light, occasionally), and the tranny seems to shift a little better everywhere else.

I brought this up because when I installed my rebuilt motor with resurfaced lightened flywheel, I didn't know about the washer. (4 years ago) I fought the Rev/1st gear crunching for 2 effin years!! Then I read about it on a BBS I ripped the tranny out to try it, bingo! what a difference! Damn thing shifts really nice!

Hmmm... what washer (asks the guy with very crunchy gears (IMG:style_emoticons/default/wink.gif))

Did a search for washer and crunch and didn't find anything. Could you elaborate?

The washer goes behind the pivot ball for the clutch fork in the transmission bellhousing. When the flywheel is machined, the fork needs to be moved towards the engine the same amount to preserve the geometry.

When material is removed from the flywheel for resurfacing, the clutch disc and pressure plate are recessed into the flywheel more. The throwout bearing arm must be shimmed the amount removed. This is done by adding a washer under the arm pivot. At the same time the pivot bushing should be checked or replaced as they break pretty easy. Everyone I have seen in the tranny I have used or bought have been toast (4 trannys).
